This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. For an overview of this subject see Endemism in birds.
This article covers western North America, i.e. the regions of the United States and Canada which lie west of the Great Plains.
There are no families endemic to this region.
The following genera are endemic to the region:
Most bird species which are endemic to this region have ranges which are too large to qualify for BirdLife International's restricted-range endemic status. As a result, only one Endemic Bird Area has been defined, in California.
The following is a list of species endemic to this region:
In addition, the following are endemic as breeding species:
The following species are near-endemic:
The following species spend the winter wholly within the region:
The boreal forest or taiga of the North American continent stretches through a majority of Canada and most of central Alaska, extending spottily into the beginning of the Rocky Mountain range in Northern Montana and into New England and the Adirondack Mountains of New York. This habitat extends as far north as the tree line and discontinues in mixed deciduous-coniferous forests to the south. The "taiga", as it is called there, of Eurasia occupies a similar range on those continents. Throughout the Northern Hemisphere, the boreal forest covers 2.3 million square miles, a larger area than the remaining Brazilian Amazon rain forest. Although it is largely forest, the boreal forests include a network of lakes, river valleys, wetlands, peat lands and semi-open tundra.
Shollenberger Park is a 165-acre (0.67 km2) wetland park located in Petaluma, California. Together with the 80-acre (320,000 m2) Alman Marsh, and 260-acre (1.1 km2) Ellis Creek which opened to the public in July 2009, a total of 505 acres (2.04 km2) are accessible to the public. The entirety is referred to as the "Petaluma Wetlands".
